Product description 

With the ESERA 1-Wire Multisensor Pro II you have 
acquired a professional and highly accurate 
Multisensor. Due to the new technology of the ESERA 
1-Wire Multisensor PRO sensors, the accuracy of the 
humidity readings is on average 200 - 300% higher 
compared to most sensors on the market.  
Due to the use of high quality internal sensors with 
12Bit resolution, the 1-Wire Multisensor Pro II provides 
very accurate values for temperature, relative humidity 
and air quality. In addition, the evaluation of the 
delivered measured values is enormously simplified. 
The 1-Wire Multisensor Pro II enables simple climate 
monitoring of rooms and buildings. 
The Multisensor is installed in a shapely surface-
mounted housing and fits harmoniously into modern 
furnished living and business rooms.                                            Inside view sensor 
 
Due to the generous ventilation openings, the 1-Wire Multisensor Pro II detects the climate conditions in 
rooms very directly and quickly.  
 
For all types of radiator and heating controls, an accurate temperature sensor such as the one installed in 
the Multisensor is an important actual value transmitter.  
 
The Air Humidity Sensor provides information about the humidity conditions in the living space and can be 
used to prevent mold growth. 
With the help of the Air Quality Sensor a good statement about the current air quality and hint for ventilation 
can be given. It is also the optimal sensor for controlling a ventilation system. 
 
In combination with 1-Wire ESERA Switching modules / binary outputs a very effective and energy-saving 
heating control (single room control) is possible. 
The 1-Wire Multisensor Pro II is intended for use in normal living spaces. For outdoor use and in damp 
rooms, such as sauna, steam bath or winter garden, a suitable sensor is available via the ESERA website. 
The 1-Wire Multisensor Pro II has a short warm-up time of a few minutes for the air quality value. 
The electrical connection to the 1-Wire Bus system of the 1-Wire Multisensor Pro II is made with screw 
terminals and can be operated in standard mode (3 cables for ground, data and 5V). 
Each 1-Wire Multisensor Pro II has an individual serial number. 

 

Auto-E-Connect Support 

The Multisensor Pro with production date as of 06/2021 supports Auto-E-Connect Level I, 
II and III.    
 

Auto-E-Connect® System 

With the launch of the ECO Controller, the ESERA Auto-E-Connect® 1-Wire Plug and Play system for the  
1-Wire bus is now introduced and supported.  
This now enables fully automatic configurations of 1-Wire devices (sensors and actuators) on the 1-Wire bus. 
It is optimized for commercial and industrial applications and enables significant added value beyond sensor 
and chip data. 
 
The Auto-E-Connect function is built up in three levels. Currently there are Level I, Level II and Level III 
available. 
Please refer to the "Technical data" to find out which Auto-E-Connect functionality this sensor supports. 
With Auto-E-Connect Level III, fully automatic configurations of the 1-Wire devices on the  
1-Wire Bus are possible. It is optimized for industrial and IoT applications and enables significant added 
value beyond sensor and chip data. 

Note 

Basics and tips for the 1-Wire bus system can be found in the ESERA Online Shop at
